For how long can the engine be motored (cranked)?

The correct duration for motoring or cranking an engine is crucial for ensuring that the engine receives the proper checks and maintenance without risking damage due to overheating or wear. The specified time for cranking the engine, in this case, is five minutes. This limit allows the engine to be checked for compression, fuel flow, and other critical functionalities while also safeguarding against excessive heat buildup.

Motoring the engine beyond this duration could potentially lead to mechanical failures or complications, as components may become excessively hot. The five-minute limit strikes an appropriate balance, enabling maintenance personnel to effectively check systems while avoiding the risks associated with extended periods of operation.
